Bonjour,
Je n'arrive pas à charger correctement le firmware Realtek **rtw88** pour la [carte M.2 AzureWave RTL8822CE](https://www.friendlyelec.com/index.php?route=product/product&product_id=293) sur mon [Nanopi R5C](https://wiki.friendlyelec.com/wiki/index.php/NanoPi_R5C#Hardware_Spec).
Voici la sortie de `lspci -k` :> root@nanopi:~# lspci -k
.&checktime(0000,00,00,':').0 PCI bridge: Rockchip Electronics Co., Ltd RK3568 Remote Signal Processor (rev 01)

On voit que pour le bus PCI .&checktime(0000,01,00,':').0, le module **rtw88_88ce** a bien été identifié, mais n'est pas utilisé (il manque la ligne "_Kernel driver in use_" comme les deux ports ethernet).
La sortie de `journalctl` donne :> kernel: pcieport .&checktime(0000,00,00,':').0: bridge configuration invalid ([bus 00-00]), reconfiguring

J’ai une erreur : « **error beacon valid** », mais impossible de trouver de l’information là dessus.
Pouvez-vous m'aider à comprendre pourquoi ce firmware ne se charge pas correctement ?
Je ne sais pas comment avoir plus d'informations lors de la génération des logs. Peut-être est-il possible d'avoir un mode "**debug**" ?
